Dispositif de connexion de circuits souples
La présente invention concerne un dispositif destiné à la jonction mécanique et électrique entre un circuit imprimé souple et un circuit imprimé rigide ou entre deux circuits imprimés souples dans le cadre des applications à bas courant, notamment dans le domaine automobile. Flexible circuit connection device
The present invention relates to a device for the mechanical and electrical connection between a flexible printed circuit and a rigid printed circuit or between two flexible printed circuits in the context of low current applications, particularly in the automotive field.
La soudure est souvent utilisée pour réaliser des jonctions électriques non démontables. Quand on veut une connexion démontable, on la réalise généralement par l'intermédiaire de connecteurs ("clips") métalliques équipant le premier circuit souple et de languettes métalliques équipant le second circuit (souple ou rigide) ; la pression des clips sur les languettes assure la connexion électrique. La jonction mécanique est généralement assurée par deux boîtiers plastiques appelés"porte-clips"et "porte-languettes"qui servent de réceptacles aux éléments de jonction électrique. Cette technologie de liaison électrique, initialement définie pour les forts courants est aussi en application pour les courants faibles. Or aujourd'hui, dans l'automobile, on a tendance à utiliser de plus en plus de circuits souples (ou circuits flexibles plats) qui peuvent remplacer avantageusement les faisceaux de fils. Il est donc important de tenter d'améliorer la technique de connexion démontable grâce à une technologie spécifiquement adaptée. Welding is often used to make electrical connections that can not be dismantled. When a removable connection is desired, it is generally done by means of connectors ("clips") metal equipping the first flexible circuit and metal tabs equipping the second circuit (flexible or rigid); the pressure of the clips on the tabs ensures the electrical connection. The mechanical joint is generally provided by two plastic housings called "clip holder" and "door-tongues" which serve as receptacles for the electrical connection elements. This electrical connection technology, initially defined for high currents, is also used for low currents. Nowadays, in the automotive industry, there is a tendency to use more and more flexible circuits (or flat flexible circuits) which can advantageously replace the bundles of wires. It is therefore important to try to improve the removable connection technique with a specifically adapted technology.
Afin d'éviter l'emploi de connecteurs et réduire le nombre de composants employés pour la connexion, on a déjà proposé de mettre directement en contact les conducteurs du premier circuit avec les conducteurs du second circuit (souple ou rigide) et d'assurer la continuité électrique par pression, mais généralement au prix de montages compliqués (cf. US 3319216, US 3825878, US 4468074, US 5954536, US 5934933). In order to avoid the use of connectors and to reduce the number of components used for the connection, it has already been proposed to directly contact the conductors of the first circuit with the conductors of the second circuit (flexible or rigid) and to ensure electrical continuity by pressure, but generally at the cost of complicated assemblies (see US 3319216, US 3825878, US 4468074, US 5954536, US 5934933).
Le but de l'invention est de proposer un montage simple permettant de relier efficacement et rapidement un circuit souple à un circuit souple ou rigide. The object of the invention is to provide a simple assembly for connecting efficiently and quickly a flexible circuit to a flexible or rigid circuit.
L'invention atteint son but grâce à un dispositif de connexion électrique et mécanique d'un premier circuit souple avec un second circuit rigide ou souple, du type selon lequel les conducteurs du premier circuit The invention achieves its goal by means of a device for electrical and mechanical connection of a first flexible circuit with a second rigid or flexible circuit, of the type according to which the conductors of the first circuit
<Desc/Clms Page number 2><Desc / Clms Page number 2>
sont mis en contact avec les conducteurs du second circuit et sont maintenus par une pression élastique, caractérisé en ce que la pression est exercée entre deux éléments d'un boîtier de montage sur lequel est incorporé le second circuit, le boîtier comprenant un couvercle susceptible de prendre une position d'ouverture et une position de fermeture, la position d'ouverture laissant apparaître une surface de réception du premier circuit et présentant des éléments de positionnement du premier circuit, et la position de fermeture forçant le couvercle à presser élastiquement le premier circuit contre le deuxième, le couvercle étant bloqué dans sa position de fermeture par des éléments d'encliquetage. are brought into contact with the conductors of the second circuit and are held by an elastic pressure, characterized in that the pressure is exerted between two elements of a mounting housing on which is incorporated the second circuit, the housing comprising a cover capable of take an open position and a closed position, the open position revealing a receiving surface of the first circuit and having positioning elements of the first circuit, and the closing position forcing the cover to elastically press the first circuit against the second, the cover being locked in its closed position by detent elements.
Ainsi il suffit de fermer le couvercle pour pousser de manière élastique les deux circuits au contact l'un de l'autre. Thus, it is sufficient to close the lid to elastically push the two circuits into contact with each other.
Le couvercle peut être entièrement détachable du boîtier ou, plus avantageusement, lui être relié par une charnière de préférence venue de moulage. The lid can be completely detachable from the housing or, more advantageously, be connected to it by a hinge preferably molded.
Avantageusement, la surface de réception est formée directement par une surface du second circuit, s'il s'agit d'un circuit rigide, ou bien de préférence par une surface du boîtier sur laquelle on place une partie du second circuit puis une partie du premier circuit, de manière superposée. Advantageously, the receiving surface is formed directly by a surface of the second circuit, if it is a rigid circuit, or preferably by a surface of the housing on which a part of the second circuit is placed and then part of the first circuit, superimposed.
On facilite le positionnement des circuits par des pions de positionnement auxquels correspondent des trous des circuits. Les pions servent aussi au maintien mécanique des circuits qu'ils traversent. The positioning of the circuits is facilitated by positioning pins to which holes in the circuits correspond. The pieces also serve to mechanically maintain the circuits they pass through.
De manière avantageuse, le contact est amélioré grâce à une déformation (un bossage par exemple) d'au moins un des circuits au niveau du contact souhaité. Advantageously, the contact is improved thanks to a deformation (a boss for example) of at least one of the circuits at the desired contact.
D'autres avantages et caractéristiques apparaîtront à la lecture de la description de l'invention, ainsi que des dessins annexés sur lesquels : - la figure 1 est une vue en perspective d'une pièce utilisant le dispositif conforme à l'invention, dans lequel le couvercle est à l'état fermé ; - la figure 2 est une vue plus en détail du dispositif de la figure 1, le couvercle étant ouvert et le premier circuit étant en court d'insertion. Other advantages and features will appear on reading the description of the invention, as well as the appended drawings in which: FIG. 1 is a perspective view of a part using the device according to the invention, in which the lid is in the closed state; FIG. 2 is a view in more detail of the device of FIG. 1, the cover being open and the first circuit being in short insertion.
Les figures 1 et 2 montrent un boîtier 1 en plastique moulé comportant des logements divers destinés à abriter des organes électriques FIGS. 1 and 2 show a molded plastic housing 1 comprising various housings intended to house electrical components

et mécaniques, par exemple dans le cadre d'une platine de commande pour automobile. Le boîtier 1 comporte un plateau 2 qui peut se fixer sur la pièce 1 en s'encliquetant derrière les crochets de pattes flexibles 3. and mechanical, for example in the context of a control plate for automobile. The housing 1 comprises a plate 2 which can be fixed on the part 1 by snapping behind the hooks of flexible tabs 3.
Le plateau 2 comporte une zone sensiblement plane 4, éventuellement surélevée, destinée à recevoir à plat une partie terminale 5 du circuit souple 10 lié au boîtier 1. Sur cette partie terminale 5, des bossages 6 ont été formés pour favoriser le contact avec les pistes 8 du circuit souple 7 avec lequel la connexion doit être réalisée. Dans la zone 4, rectangulaire, deux pions 9 sont placés en diagonale et servent au positionnement correct de la partie terminale 5 du circuit souple 10 qui est retourné sur un bord 11 du plateau 2. Le reste du circuit souple 10 est dissimulé sous le plateau 2. The plate 2 comprises a substantially flat area 4, possibly raised, intended to receive a flat end portion 5 of the flexible circuit 10 connected to the housing 1. On this end portion 5, bosses 6 have been formed to promote contact with the tracks 8 of the flexible circuit 7 with which the connection must be made. In zone 4, rectangular, two pins 9 are placed diagonally and serve to correctly position the end portion 5 of the flexible circuit 10 which is returned to an edge 11 of the plate 2. The remainder of the flexible circuit 10 is hidden under the tray 2.
Un couvercle 12 est moulé avec le plateau 2 auquel il est relié par une charnière moulée 13. La charnière 13 est placée le long du côté arrière de la zone 4 de manière à pouvoir placer le couvercle 12 en position de fermeture au-dessus de ladite zone 4. Le couvercle comprend une partie intérieure sensiblement plane 14 sur laquelle est prévue une épaisseur 15 d'élastomère (caoutchouc de silicone, par exemple) parallèle à la charnière 13. Le couvercle 12 comporte des trous ou des évidements 16 destinés à recevoir l'extrémité des pions 9 et d'autre part, il comporte aux extrémités de son bord 17 opposé à la charnière 13 deux pattes d'accrochage 1 8 dont les crochets 19 peuvent venir s'encliqueter dans deux évidements 20 du plateau 2. A lid 12 is molded with the plate 2 to which it is connected by a molded hinge 13. The hinge 13 is placed along the rear side of the zone 4 so as to be able to place the lid 12 in the closed position above said zone 4. The cover comprises a substantially flat inner part 14 on which is provided a thickness of elastomer (silicone rubber, for example) parallel to the hinge 13. The cover 12 has holes or recesses 16 for receiving the end of the pins 9 and secondly, it has at the ends of its edge 17 opposite the hinge 13 two latching lugs 18 whose hooks 19 can snap into two recesses 20 of the plate 2.
Lorsqu'on vient disposer l'extrémité 21 du circuit souple 7 audessus de la zone de réception 4, on engage les pions 9 dans les trous 22 prévus à cet effet pour positionner l'extrémité 21 de circuit, et l'on vient refermer le couvercle 12 sur la zone 4 de manière à appuyer élastiquement, grâce à la couche d'élastomère 15, sur les deux extrémités superposées 5 et
21 des circuits. Afin d'assurer une bonne pression, le couvercle peut être renforcé par une surépaisseur 23 au niveau de la couche d'élastomère.When the end 21 of the flexible circuit 7 is placed above the reception zone 4, the pins 9 are engaged in the holes 22 provided for this purpose in order to position the end 21 of the circuit, and the end is closed again. cover 12 on the zone 4 so as to support elastically, thanks to the elastomer layer 15, on the two superimposed ends 5 and
21 circuits. In order to ensure a good pressure, the cover may be reinforced by an excess thickness 23 at the level of the elastomer layer.
